Iran Press/ Middle East: Spain is going up against Morocco first, while two European teams -- Portugal and Switzerland -- will go head-to-head later in the day.
Morroco is hoping to defeat Spain on the pitch today at 16:00 CET.
This will be the second World Cup meeting between the two sides. Spain has never lost in the three last meetings with Morroco and is tipped to win. But this has been a World Cup of surprises and nothing can be said for certain.
Morroco is featuring in the knockout stages of the World Cup for only the second time. In 1986, they reached round 16, losing to Germany 1-0.
While he hopes it won't come down to it, Spain's coach Luis Enrique has said his team is preparing for a possible penalty shoot-out with Morroco.
